The Java Service Wrapper makes very easy to install a Java Application as a daemon process on Unix systems. The Wrapper monitors a JVM (Java Virtual Machine) process and automatically restarts it if it that the JVM has crashed or hung. This process takes just a few seconds once the Wrapper has decided there is a problem. It also gives the ability to handle process priority. AUTHOR
